The modern theory that starvation is due to an increase in population is not accepted by the demigods or the devotees of the Lord. The devotees or demigods are fully aware that the Lord can maintain any number of living entities, provided they are conscious of how to eat. If they want to eat like ordinary animals, who have no God consciousness, then they must live in starvation, poverty and want, like the jungle animals in the forest. The jungle animals are also maintained by the Lord with their respective foodstuffs, but they are not advanced in God consciousness. Similarly, human beings are provided with food grains, vegetables, fruits and milk by the grace of the Lord, but it is the duty of human beings to acknowledge the mercy of the Lord. As a matter of gratitude, they should feel obliged to the Lord for their supply of foodstuff, and they must first offer Him food in sacrifice and then partake of the remnants.
(Srimad Bhagavatam-----3:5:49-----purport).

The human society should give more attention to animal protection. The productive energy of the laborer is misused when he is occupied by industrial enterprises. Industry of various types cannot produce the essential needs of man, namely rice, wheat, grains, milk, fruits and vegetables. The production of machines and machine tools increases the artificial living fashion of a class of vested interests and keeps thousands of men in starvation and unrest. This should not be the standard of civilization.
(Srimad Bhagavatam-----1:9:26-----purport).

The living being is the source of subsistence for other, stronger living beings. No one should be very anxious for his subsistence in any circumstances because there are living beings everywhere, and no living being starves for want of food at any place. Mahārāja Yudhiṣṭhira is advised by Nārada not to worry about his uncles' suffering for want of food, for they could live on vegetables available in the jungles as prasāda of the Supreme Lord and thus realize the path of salvation.
(Srimad Bhagavatam-----1:13:47-----purport).

The other species of living entities, who far outnumber human society, are never disturbed for maintenance; they are never seen dying of starvation. It is only human society that is disturbed about the food situation and, to cover up the real fact of administrative mismanagement, takes shelter in the plea that the population is excessively increasing. If there is any scarcity in the world, it is the scarcity of God consciousness, otherwise, by the grace of the Lord, there is no scarcity of anything.
(Srimad Bhagavatam-----3:5:5-----purport).

In Bhagavad-gītā (3.13) it is confirmed that one who takes foodstuff after a performance of sacrifice eats real food for proper maintenance of the body and soul, but one who cooks for himself and does not perform any sacrifice eats only lumps of sin in the shape of foodstuffs. Such sinful eating can never make one happy or free from scarcity. Famine is not due to an increase in population, as less intelligent economists think. When human society is grateful to the Lord for all His gifts for the maintenance of the living entities, then there is certainly no scarcity or want in society. But when men are unaware of the intrinsic value of such gifts from the Lord, surely they are in want. A person who has no God consciousness may live in opulence for the time being due to his past virtuous acts, but if one forgets his relationship with the Lord, certainly he must await the stage of starvation by the law of the powerful material nature. One cannot escape the vigilance of the powerful material nature unless he leads a God conscious or devotional life.
(Srimad Bhagavatam-----3:5:49-----purport).

Starvation can be mitigated by drinking water. It is sometimes found that if a person who has taken a vow to fast takes a little water at intervals, the exhaustion of fasting is at once mitigated. In the Vedas it is also stated, āpomayaḥ prāṇaḥ: "Life depends on water." With water, anything can be moistened or dampened. Flour dough can be prepared with a mixture of water. Mud is made by mixing earth with water. As stated in the beginning of Śrīmad-Bhāgavatam, water is the cementing ingredient of different material elements. If we build a house, water is actually the constituent in making the bricks. Fire, water and air are the exchanging elements for the entire material manifestation, but water is most prominent.
(Srimad Bhagavatam-----3:26:43-----purport).

That which happened during the time of Pṛthu Mahārāja and his father, King Vena, is also happening at this present moment. A huge arrangement exists for the production of large-scale industrial and agricultural products, but all these products are meant for sense gratification. Therefore despite such productive capacities there is scarcity because the world's population is full of thieves. The word corī-bhūte indicates that the population has turned to thievery. According to Vedic understanding, men are transformed into thieves when they plan economic development for sense gratification. It is also explained in Bhagavad-gītā that if one eats food grains without offering them to the Supreme Personality of Godhead, Yajña, he is a thief and liable to be punished. According to spiritual communism, all properties on the surface of the globe belong to the Supreme Personality of Godhead. The population has a right to use goods only after offering them to the Supreme Personality of Godhead. This is the process of accepting prasāda. Unless one eats prasāda, he is certainly a thief. It is the duty of governors and kings to punish such thieves and maintain the world nicely. If this is not done, grains will no longer be produced, and people will simply starve. Indeed, not only will people be obliged to eat less, but they will kill one another and eat each other's flesh. They are already killing animals for flesh, so when there will no longer be grains, vegetables and fruits, they will kill their own sons and fathers and eat their flesh for sustenance.
(Srimad Bhagavatam-----4:18:7-----purport).

The modern theory of dialectical communism, set forth by Karl Marx and followed by communist governments, is not perfect. According to Vedic communism, no one in the state should ever starve. Presently there are many bogus institutions which are collecting funds from the public for the purpose of giving food to starving people, but these funds are invariably misused. According to the Vedic instructions, the government should arrange things in such a way that there will be no question of starvation. In the Śrīmad-Bhāgavatam it is stated that a householder must see to it that even a lizard or a snake does not starve. They also must be given food. In actuality, however, there is no question of starvation because everything is the property of the Supreme Lord, and He sees to it that there is ample arrangement for feeding everyone. In the Vedas (Kaṭha Upaniṣad 2.2.13) it is said: eko bahūnāṁ yo vidadhāti kāmān. The Supreme Lord supplies the necessities of life to everyone, and there is no question of starvation. If anyone starves, it is due to the mismanagement of the so-called ruler, governor or president.
